Uniqlo Color: White Size: 90 Since it's white, you might be concerned about dirt, but there are no major black marks, stains, or dirt that I can see. There is some slight pilling. GU Color: Pink Size: 90 There is also some slight pilling, but no major noticeable stains. It's thinner than the Uniqlo item and was wearable even in the slightly cooler summer months. Although it's for a boy, he wore both the white and pink items stylishly.
